From a PPRC (shiny surface) pipe with an inner diameter of 20.5 mm and a length of 70 cm, water at 20 ° C flows at a flow rate of 1500 L / h and a pressure difference of 52 mbar occurs. Based on these data, find the speed of the water, the Re number, the friction factor, the f value and the pressure difference (in mbar) and show the f value you found from the Moody diagram. (For 20 ° C water; p = 998 kg / m3,µ= 1.003x10-3 N.s / m2, v = 1.005x10-6 m2 / s, 1 bar = 10.2141mSS)
